- Application mearebrary 3,1920. serial No. 355,920;

To' all 'whom it may concern: Be itknown that I, JOHN .a citizen of the United States, and a resident of Columbus, in the `"county of Franklin and State of-Ohio, have invented cbrtain 'newl and useful Improvements in Car- Trucks; and I do hereby declare the follow# ing to be a full, clear, .and exact description of the invention, such as will enable others skilledin the art'to which it appertainsto make and usethe same.

This invention relates to improvements in car trucks and more particularly to that part ofthe structure which provides meansl for supporting the hangers for the outer brake shoesf-one object of the `invention being to provide brackets for the outside brake-shoe. hangers ywhich ,shall .be made separate from. the side frames and secured thereto'witho'utthe use (if-bolts or rivets nal boxes with the'y side frames. v

A further object ,is toprovide a structure wherein the bl'afkeishoe hanger brackets or castings shalli-bfheld in rigid relation relatively to thef'sideframes, by the weight of the side frame loadAwhich is transmitted to Athe-journal boxesgbyl the action of the journal box bolts; and by intermeshing connections betweensaid brackets and the side frames.

With these and other objects in view, the invention consists in certain novel features of construction fand combinations of .parts as hereinafterlset forth and pointed out in the claims.- f

In theA accompanying drawingsj Figure 1 isa side elevation ofa truck showing an embodiment of my partial plan'view; Fig. 3 is an enlarged sectional view showing a portion of afsde frame and a brake hangerl bracket secured theretoplFig. 4 is aview showing one end` of a side frame and brake hanger bracket separated therefrom, and Fig. is a sec-` tional view'on the line 5 5 of Fig. 3.

`1 represents a truck side frame, 2 the wheels, 3 the journal boxes, and 4, 4 the journal box bolts,-the latter being secured.

invention; Fig. 2 is a mately in line with ,provided with iateri arms 7,10 which brackets 8 may be secured to receive hangers 8a for the inside brake sho`es9. f

At respective endsfthe side frame 1 is made with tapering extensions 10, the free end of each ofwhich are beveled as at 1,1

andvunder said extensions, seatsare afforded for the journal boxes. AThe side frame 1 may' bemade .hollow vand the bottom`mem- .ber of each extension 10 is made with holes 12, 12,- to receive the vupper ends of the jourfree ends with lateral larms 15 With. .which hangersll for. the outer brake shoes 17 are connected. Each bracket 14 i's provided in its bottomv with' a hole .18 to receive the journal box bolt 4 and in its top with an opening 19 through which access may be had to a nutv or head at the upper 'end-of said bolt. At its inner end, 'the lower member ,of the bracket 14 is' made with a notch 20 for the Aaccommodation'`of"the journal box'bolt 4,

and the upper member 4ofthe side frame is made with any'openin'g 21 through. which access may be-had to a nut or head at the upper end of said'bolt 4F. The inner end of the bracket 14 is beveled as shown at 22',

and the upper member of said bracket is made with -an opening 23 which accommodates the top ofthe extension 10 ofthe side 1 frame 1. Between the hole 18 'and notch 20- vin the bottom' member of the bracket 14,

said bottom member is provided withv a lug 24 which enters the hole 13 in the bottom member of the side frame extension 10. One side of the taperingextension 10 liesagainst .one side: of the. hollow bracket 14 'and in order to prevent possibilityof lateral displacement'of lsaid bracket, the frame extension l0 is made with a lateral enlargement 25, which lies closely against the opposite side 'wall' ofthe bracket,-said last mentioned Wall ofthe bracket being approxithe inner wall of the side frame l.

It will be observedthat Withmy improvements the brackets for the outside' brakeshoe hangers are made separate from the side frames and secured thereto and that they are secured to the side frame by means ofthe journal box halter-thus obviating ne frame.

cessity for the use of additional bolts or rivets for securing said brackets to the side It willmalso be observed that the brackets 14 are held in rigid relation to the side frames by the weight ofthe side frame load which is transmitted toA the journal boxes; by the action of the journal Ibox bolts b y the engagementvof the 'lug 2li in the bracket in the hole 13 .in the frame extension 10,`and by the lateral enlargement 25 on said?v extension closely tting the inside Y wall of the. bracket 14.

The invention is applicable for use with both. four and siX wheel trucks and while I have illustrated this improvement in connection with frames for our wheel truck Y construction it is not with the intention of limiting its application to vsuch side frames or any other particularconstruction of side ,Set forth.

Having fully described my invention what I claim as new and desire to secure by Letters-Patent, is

1. The combination with a truck side frame, and a journal box, of a brake-shoe hanger bracketmounted on said side frame and provided at its free end with a lateral arm t0 receive a brake-shoe hanger, and journal box bolts securing said bracket to the side frame.

2. The combination with a truck side frame, 0f a brake-shoe hanger bracket having interlocking connection Iwith said side frame, a journal box below said bracket, and journal box bolts securing said bracket to said side frame.

' 3. The combination with a truck side frame having an end extension, said eXtension having a hole in its bottom, of a brakeshoe hanger bracket receiving said frame extension and having a lugv entering the hole in the bottom thereof, and bolts securing said bracket to said frame extension.

4. The combination with a truck .side frame having an en d extension, of a hollow .brake-shoe-hanger bracket receiving said eX- tension, said extension. having a lateral en largement lying against a side wall of said hollow bracket, and bolts securing said bracket and frame extension together.

5. The combination `with a truck side frame having an end extension, of aphollow brakeeshoe hanger bracket receiving said frame extension and having interlocking connection therewith, a bottom journal box bracket secured to the side frame, a journal box between said bottom bracket and the bottom of said first mentioned bracket, and bolts passing through said bottom bracket, the first-mentioned bracket and said side frame extension.

'11n testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
